What molecules move with endocytosis and exocytosis as opposed to diffusion or active transport?
Large molecules or particles such as proteins, lipids, polysaccharides, and even whole cells are typically transported through endocytosis and exocytosis, as they are too large to pass through the cell membrane via diffusion or active transport. Endocytosis brings substances into the cell by engulfing them in a vesicle, while exocytosis expels substances out of the cell by merging vesicles with the cell membrane.
What are two things water is used for in animals?
animals need water to drink. they can also go inside to swim or washA:In animals, water is the solvent that fills the cells, as well as the solvent in the blood. Within the cells, it provides structure to the cells, and a transport mechanism for molecules and nutrients around the cells.Between the cells and in the blood, it also provides a transport mechanism for nutrients, cellular waste, and various other needs of the body, including the movement of whole cells.On mucous membranes, it provides a barrier to prevent the cells from drying out, and a significant amount is lost providing this function, especially in the lungs.It is also a solvent for the excretion of nitrogen and water soluble salts in the kidneys (Urine).Water is a vital part of digestion, and provides a medium for food to be broken down in the digestive tract, as well as being transported along the digestive tract. Much of it is reabsorbed in the large intestine, although some will remain in the stools.I believe that water is consumed in some metabolic stages, but there is a net production of water by the bodies metabolism through the conversion of hydrocarbons into carbon dioxide and water.
What is the function of the specialized cells in the outer walls of the plant roots?
The specialized cells help to facilitate diffusion of substances into the plant (especially mineral ions and water). However the whole root system serves this process through acrive transport of the mineral ions which creates a diffusion gradient.
What is the type of transport that oxygen move from the alveoli into the pulmonary capillary blood?
Oxygen diffuses from the alveoli into the blood due to higher PO2 (partial pressure of oxygen) levels in the alveoli than in the blood.
How many slaves did the french transport over the whole slave times?
900000
What is plasmodesmata?
Plasmodesmata is an organelle that can only be found in Plant cells. It basically connects all the cells together. There is more madness to the logic like why it is connected, and what is transported in the Plasmodesmata. But for now that is all you need to know.
Are microtubules found in both plant and animal cells?
Yes, microtubules are found in both plant and animal cells. They are part of the cytoskeleton, providing structural support and playing essential roles in cell division, intracellular transport, and cell shape maintenance in both types of cells.
What is the least important mechanism of heat transfer in the whole atmosphere?
Conduction is the least important mechanism of heat transfer in the whole atmosphere. It is less efficient in transferring heat because the air is a poor conductor, and convection and radiation are the dominant mechanisms of heat transfer in the atmosphere.
Do stomachs have cells inside of them?
Yes, your whole body does.
The mixture of plasma and blood cells is called?
Hematocrit is the proportion of your total blood volume that is composed of red blood cells. If you add the plasma, what you have is a blood sample called a full blood count.
How do you change window motor in 2000 Toyota Camry?
For that you will have to remove the whole window mechanism. Then you will be able to replace the motor. When you assemble the mechanism make sure that you have set up position of the gears properly.
Whole blood is packed with what?
Whole blood is made up of 3 parts - red blood cells, plasma and a Buffy coat which contains white blood cells and platelets.
